The health problems of gold miners who worked underground include the decrease in life expectancy; the increase in the frequency of cancers of the trachea, bronchi, lungs, stomach and liver; the increase in the frequency of pulmonary tuberculosis (PTB), silicosis and pleural diseases; the increase in the frequency of insect-borne diseases, such as malaria and dengue fever; the loss of noise-induced hearing; the increase in the prevalence of certain bacterial and viral diseases; and diseases of the blood, skin and the musculoskeletal system. These problems are briefly documented in gold miners in Australia, North America, South America and Africa, as well as those who mine IRA Gold and Silver. In general, HIV infection or excessive consumption of alcohol and tobacco tended to aggravate existing health problems. Miners who used elemental mercury to amalgamate and extract gold were heavily contaminated with mercury. Among those who are occupationally exposed, mercury concentrations in air, fish diets, hair, urine, blood and other tissues significantly exceeded all criteria proposed by several national and international regulatory agencies for the protection of human health.
However, large-scale epidemiological evidence of serious mercury-related health problems could not be demonstrated in this cohort. Sometimes, the contamination is so severe that large quantities of chemicals are needed to treat water, which can affect the quality of the water supplied to the public, and water companies may have no other option but to shut down operations. However, this would depend on the CEC and the mineral composition of soils, since they determine the mobility of heavy metals in the environment and are affected by prevailing pH conditions. Similar to human toxicity, the mass fraction of metal emission to soil that reaches freshwater was combined with the effect factors of aquatic ecotoxicity in freshwater in UseTox to quantify factors characterizing freshwater ecotoxicity.
The contamination factor of each heavy metal at each site (Cf) and the degree of contamination by heavy metals at each of the three sites (Cdeg) were determined according to the equations (and (, respectively). In Ghana, the endemic nature of Buruli ulcer in communities adjacent to mining activities suggests that proximity to artisanal and small-scale gold mining (ASGM) is a risk factor for this disease, as is the higher prevalence of Buruli ulcer in Amansie West district. Known as Ghana after independence in 1957, the extraction of gold and other resources continues and contributes greatly to economic development. The human health effects of gold mining by cyanide leaching are not well documented, and this is no exception in Montana.
Many of the heavy metals and metalloids released by gold mining activities are toxic to plants and have the capacity to bioaccumulate, posing health risks to humans, animals and ecosystems. Therefore, the present study aimed to determine the health risks associated with the exposure of residents of the tailings landfill sites of the Au Mine to heavy metals. This operation eventually led to the discovery of the richest gold and copper vein in the world, which is located near the edge of the park. According to Kaasalainen and Yli-Halla, heavy metals emitted from anthropogenic sources, including mining activities, are highly mobile in the soil environment and have a greater potential to cause ecological and human health complications compared to those of geogenic origin.
Environmental impacts include noise pollution caused by heavy trucks in mining centers, contamination of water bodies by chemicals such as arsenic, mercury and cadmium derived from the refining of extracted minerals, pollution of agricultural soils by heavy metals and other pollutants, resulting in the depletion of agricultural land, reduced food productivity due to land sterility and exhaustion Wildlife loss due to the clearing of forests which serve as a habitat for many animal species. . .
